====默认不支持中文
# pacman -S ibus
# pacman -S ibus-qt
$ pacman -Ss ^ibus-* //查看所有可用的输入法：
# pacman -S ibus-libpinyin
# pacman -S ibus-googlepinyin
启动
$ ibus-setup
现在运行ibus-setup的初始程序(当要用Ibus的用户):
IBus has been started! If you cannot use IBus, please add below lines in $HOME/.bashrc, and relogin your desktop.
（译：IBus已启动！如果您还不能用Ibus,请您先将以下的三行代码加到$HOME/.bashrc，再重新登录。)
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
注意: 虽然Ibus使用一个后台程序，但是它不是被systemd管理的那种后台程序：普通用户也可以运行，当你登录时，它会启动。
注意: 但是，如果ibus尚未启动，先将那些"export"的代码复制到$HOME/.xprofile，并将这行代码加到该文件：“ibus-daemon -x -d”,再重新登录。
ibus-daemon -x -d
